Vehicle Network Architecture (VNA)
The communication and data framework connecting all electronic components in a vehicle.
VNA defines how ECUs, sensors, and controllers communicate through CAN, LIN, FlexRay, or Ethernet. Modern architectures use centralized domain controllers to simplify wiring and enhance efficiency. Software-defined structures allow easier updates and modular scaling. The shift toward zonal architecture reduces weight and cost while improving cybersecurity. A robust network backbone ensures real-time performance for all critical vehicle functions.
